Abstract

We investigate the relationship between two epistemic nonmonotonic formalisms: autoepistemic logic and introspective circumscription. Finitely axiomatized autoepistemic theories are shown to be equivalent to the propositional case of introspective circumscription. This theorem is applied to the problem of relating the usual "minimizing" circumscription to autoepistemic logic.
